When I dial a number the screen goes black, but the call continues.

When pressing the on-off button, the screen comes back on for about 1/2 second, then goes away again.

This is frustrating as I can't end calls (can't see the keypad) and I can't navigate mail menu systems (again, can't see the keypad).

Finally, after the call terminates, I'm able to get the normal screen to come back up. Am I doing anything wrong?

Has anyone else experienced this?

It is a really annoying issue

Screen goes black when calling or receiving calls

Remove your screen protector if you have one.
